        ### Serverless Function Timeouts

        When deploying to serverless platforms (Vercel, AWS Lambda, etc.), be aware that default function timeouts may be too short for CopilotKit's streaming responses:

        - Vercel defaults: 10s (Hobby), 15s (Pro)
        - AWS Lambda default: 3s

        **Solution options:**
        1. Increase function timeout:
            ```json
            // vercel.json
            {
              "functions": {
                "api/copilotkit/**/*": {
                  "maxDuration": 60
                }
              }
            }
            ```
        2. Use [Copilot Cloud](https://cloud.copilotkit.ai/) to avoid timeout issues entirely
